If you're diving into the world of performance clutches, the ACT HD/Race Sprung 6 Pad Kit (GM2-HDG6) is a solid choice that packs a punch. This kit comes with ACT's heavy-duty pressure plate, which is a favorite among gearheads for good reason. The unique diaphragm design isn’t just a fancy term; it actually cranks up the clamp load, cuts down on deflection, and helps your clutch last longer in the heat of battle. Each diaphragm goes through a rigorous four-stage heat-treating process, so you know it’s built to handle the pressure.
One of the standout features is the precision cover stampings on the pressure plate, which add a level of rigidity and consistency that you can feel when you're shifting. Now, let’s talk about the 6-pad, spring-centered race disc. It’s designed to dampen torsional vibrations, which means you can push your ride harder without worrying about failure. Sure, engagement can be a bit harsher, but that’s the trade-off for faster shifts and a more responsive feel. If you’ve got a high-horsepower setup, this disc is a must; it’s built to absorb more heat and keep you in the game.
Installation is straightforward, but if you need a hand, you can check out the install instructions here.
